Small Solar Cell 24 x 33mm, 4.5V, 18mA

This is a great solar panel which outputs a high enough voltage to directly drive electronic circuits or charge batteries.

The panel is built on a sturdy PCB substrate and is epoxy encapsulated to withstand rough handling.

The PCB includes solder pads to populate a simple "Miller Solarengine" which lets you pulse-power high current draw devices, like motors and electromagnets, that would otherwise require a large number of parallel cells. The addition of the circuit pads does not interfere with using this as a simple solar panel.
